Solution Overview

Problem

Cordless power tools stored in storage units often have batteries that are low on power after use, requiring recharging, and existing charging solutions leave tools and batteries susceptible to theft or damage when charging outside a locked storage unit.

Innovation Solution

A tool storage unit with integrated power outlets and a retractable power cable system that allows for secure charging within the unit, minimizing damage and theft risks by providing accessible power while preventing cable damage during drawer movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power outlets are integrated into movable drawers for charging tools and batteries, then security against theft and damage is improved, but cable damage risk increases due to repeated opening and closing movements

Engineering Contradiction:
Improvesecurity against theft and damageVSAvoidcable damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The power cable is replaced with a dynamic coiled spring mechanism that can extend and retract automatically. The spring expands to allow drawer movement and contracts to prevent cable damage, providing both security and flexibility without the harm of traditional fixed cables.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cable's physical state is changed from a rigid or fixed-length form to a coiled spring form that can dynamically change its length and configuration. This parameter change allows the cable to accommodate drawer movement while preventing damage through its elastic properties.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If power outlets are accessible in closed drawers, then convenience of charging is improved, but cable management complexity increases

Engineering Contradiction:
Improveconvenience of chargingVSAvoidcable management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coiled spring cable system is designed to automatically extend when the drawer opens and retract when it closes, without requiring manual intervention. The spring's inherent elastic properties enable self-service cable management, maintaining convenience while reducing complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The dynamic spring mechanism automatically adjusts cable length based on drawer position, eliminating the need for complex manual cable routing or adjustment mechanisms. This dynamic adaptation simplifies the overall system while maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics
